Title: Fuel feed control method of internal-combustion engine equipped with e.g.r. controller
Inventor: OTOBE YUTAKA
IPC: F02D41/24
Filed: 1982-07-08
Abstract: PURPOSE:To improve the fuel consumption characteristic and exhaust gas characteristic by reading the burning/injection time from one group in a plurality of burning/injection time groups in accordance to the operating state of E.G.R. controller. CONSTITUTION:E.G.R. 0 under fully closed state of a solenoid valve is detected in step 1 to read out the basic fuel injection time Ti from TM map in step 2. When the ratio of E.G.R. against suction is low, the basic fuel injection time Ti is read out from the first TEM in step 5. When the ratio of E.G.R. against suction is high, Ti is read out from second TEM map in step 6. Consequently the fuel consumption characteristic and exhaust gas characteristic can be improved.

Filed: 1979-09-17
Abstract: PURPOSE:To obtain a detecting circuit that facilitates impedance matching, has a high gain and is less in distortion, by obtaining a demodulated signal from a common emitter by supplying two outputs of differential amplifiers to bases of two common emitter type connected transistors. CONSTITUTION:Differential amplifiers (Q1, Q2, R2, and R3) have resistance R1 as a constant current source and an input signal is applied to bases of detecting transistors Q5 and Q6. Transistor Q7 as an impedance converter connects an output AM-detected by trnsistors Q5 and Q6 to low-pass filter (R12, C2). Detecting transistors Q5 and Q6 are turned on by turns with outputs of trnsistors Q1 and Q2 and specially in case of IC-implementation, detection operation that outputs a detection output after smoothing by the parasitic capacity between the emitters of transistors Q5 and Q6 and the earth potential is provided. Consequently, the electric power of higher harmonics generated in the detection is small, which is advantageous to whistle ratio characteristics, etc.

Abstract: PURPOSE: To mass-produce SCRs without the need of the vapor deposition of Al, etc., by covering the mouth of a formed mesa groove with a mask plate and then by adhering heavy metal.  
     CONSTITUTION: At the time of forming the PN - PN structure, mesa grooves 7 are formed on both the sides of substrate 1 by using SiO 2  film 8 as a mask. Film 8 is removed, the mesa groove on the main surface at one side is covered with mask plate of Mo, etc., and gold 3 is vapor-deposited. Next, mask 10 is removed, gold is diffused, and remaining gold is removed. Then, glass powder is supplied into groove 7 and baked to form protective film 11. Further, electrodes 4 to 6 are provided and separated to make SCR pellets. In this constitution, since no gold is vapor-deposited on the mesa groove where the (pn) junction is exposed, the trap level by gold in the depletion layer is small and a leak current will not increase. In addition, the formation and removement of an Al mask are not required, so that excellent mass-production can be attained

IPC: F02D41/14
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To purify exhaust satisfactorily in a three-way catalyst. SOLUTION: An upper reaches air-fuel ratio sensor is arranged in an exhaust passage on the upper reaches of a three-way catalyst, and an lower reaches air-fuel ratio sensor is arranged in the exhaust passage on the lower reaches of the three-way catalyst.

A second feedback correction factor is computed on the basis of deviation FBSR between the smoothing value VDSM and the output voltage VD of the lower reaches air-fuel ratio sensor.  The first feedback correction factor is corrected by the second feedback correction factor, and the fuel injection quantity is corrected by the corrected first feedback correction factor.

Title: Detecting system for collision of optical transceiver
Inventor: OKADA AKIHIRO
IPC: H04B10/079
Filed: 1987-05-15
Abstract: PURPOSE:To surely detect the collision of signals, by detecting the fact of the disconnection of the signal representing a state in receiving while the signal is transmitted, and detecting the signal different from its own transmission signal at a bit comparison part which compares the transmission signal and a reception signal sequentially. CONSTITUTION:The transmission signal and the reception signal are inputted to a signal reproduction parts 4 and 3, and clocks CLK-S and CLK-R are extracted, and data decoded at a Manchester code side is reproduced and outputted. Also, the signals DS-S and DS-R representing the state in decoding the data of the transmission signal and the reception signal are sent. In a disconnection detection part 1, when the momentary disconnection or the disconnection of the signal DS-R is generated in decoding the transmission signal, the CLK-R performs autonomous run of 2-3 bits, and latches the momentary disconnection or the disconnection, and outputs a collision detection signal to an OR6. A FIFO5 reads out the transmission signal stored in the CLK-R, and compares it with the data of a reception signal reproduction part 3 at the bit comparison part 2, and when they are different, sends a collision signal to the OR6. In such a way, it is possible to surely detect the collision.

Filed: 1987-05-15
Abstract: PURPOSE:To obtain a MIS transistor having excellent breakdown strength which is unaffected by a highly concentrated diffusion layer by forming a highly concentrated impurity diffusion layer to be used to compensate for ohmic contact through a polycrystalline semiconductor film located on source and drain diffusion layers. CONSTITUTION:A polycrystalline semiconductor film which is in contact with respective source and drain diffusion layers of a MIS transistor is formed and an impurity region for forming applications of ohmic contact having an impurity concentration which is thicker than those of the source and drain diffusion layers is selectively formed. For example, compensating diffusion layers 17 and 18 which make the contact of source and drain ohmic are formed through the second polysilicon films 15 and 16. Then, no diffusion layers 17 and 18 are formed to have depths which are deeper than those of the source and drain diffusion layers having a low concentration of impurities so as to keep breakdown strength to a high degree. As a result, a MOS transistor having excellent breakdown strength can be set univocally by the impurity concentration for forming applications of source and drain.

Title: Synchronizing system for key telephone device
Inventor: DOI AKIO
IPC: H04M1/72
Filed: 1981-08-03
Abstract: PURPOSE:To ensure the synchronism of a telephone, by transmitting continuously a certain number of signals opposite to the start bit before said start bit of a control signal sent to the telephone from a main device and then receiving the start bit after the signal opposite to the start bit is received to detect the inversion of a receiving circuit. CONSTITUTION:The FS signal to be given to a telephone 2 from a main device 1 is fed to the telephone 2 after an audio signal is multiplexed with a power supply through an extension line 4 based on the clock signal SCM. For this multiplexed signal, both the power supply and the audio signal are deleted through an HPF8 and only the FS signal is applied to an FS receiving circuit 7. The FS signal digitized through the circuit 7 is supplied with inversion to a microcomputer 5 and the reset terminal of a counter circuit 10 that detects the (1X8) continuation. When the output of the counter 10 is 1, the FS signal is regarded as a synchronizing signal by the computer 5 according to the signal state of the terminal P0 of the computer 5. Then the start bit is monitored, and the timing of a transmitting circuit is corrected by a transmitting shift clock generating circuit 9. Thus the synchronism of transmission is obtained between the device 1 and the telephone 2.
